The aim of this study was to determine the activity of digestive enzymes during the fry development of Rainbow trout ( Oncorhynchus mykiss ), which has a remarkable role in food digestion and absorption in the first feeding. The assessment of digestive enzymes activity of gastric (pepsin), pancreatic (trypsin, chymotrypsin, α-amylase and lipase) and intestinal (alkaline phosphatase) revealed t...
according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
most specialists in the field of foreign language teachingconsiderreading skill as an interactive process between the reader’s prior knowledge and the text.accordingly, the activation of prior knowledge for an effective comprehension is very important. it is generally agreed that the pre-reading phase is the stage where this type of interaction and activation may be enhanced throughcertain stra...
The aim of the present study was to investigate the effect of Lactococcus lactis and Weissella cibaria probiotics on growth performance, intestinal bacterial flora, digestive enzymes and intestinal histology in common carp (Cyprinus carpio). Fish with an average initial weight of 17 g were divided into 10 treatments with 3 replications. Fish food in treatments 1, 2 and 3 were supplemented with ...
An experiment was conducted to evaluate the effects of wheat and wheat bran diets with and without enzymes on growth performance and digestive characteristics of broilers. A total number of 625 one day old Ross-308 broiler chickens were allocated randomly to 5 treatments with 5 replicates, using a CRD statistical design. Treatments were control, wheat, wheat+ enzyme and wheat bran and wheat bra...
This study was conducted to determine effects of dietary administration of different levels of ginger (Zingiber officinale) extract on digestive enzymes activity and liver composition of Mesopotamichthys sharpeyi during eight weeks. In this respect, 192 M. sharpeyi fingerlings (with initial weight 11.67 ± 0.32 g) were divided into three ginger extract (0.1%, 0.5%, 1%) treatment group...
the impact of three different fabaceous host plants including cowpea (vigna unguiculata), chickpea (cicer arietinum), and mung bean (vigna radiata) seeds was investigated using biochemical approaches on possible changes of gut proteolytic activity of the cowpea weevil, callosobruchus maculatus at 30±1˚c and 70±5% rh and a photoperiod of 8:16 (l:d). results revealed that ph of 4-5 and 9 was opti...
the cotton bollworm, helicoverpa armigera (hübner), is a serious pest on a wide range of economic crops in many parts of the world. in this study, digestive proteolytic and amylolytic activities of h. armigera larvae (3rd to 5th instars) were evaluated on five main host plants including chickpea (cv hashem), cowpea (cv mashhad), soybean (cv 033), navybean (cv dehghan), and corn (cv sc 704) at 2...
The recent study carried out to investigate digestive enzymes and blood biochemical parameters in farmed Huso huso juveniles feeding diet containing different levels of Nacl. This experiment includes 4 treatments. The Nacl added in 4 levels of 0, 3, 6 and 9 percent in to the main diet. In this regard 480 species of farmed Huso huso with mean weight of 175g and 5 months old, placed in 12 fibergl...
